[en] The masses of positive parity [70,0(+)] and [70,2(+)] nonstrange and strange baryons are calculated in the 1/N-c expansion. The approach is based on the separation of a system of N-c quarks into an excited core and an excited quark. The previous work for two flavor baryons is now extended to include strange baryons, to first order in SU(3)-flavor breaking. We show that the extension to N-f=3 maintains the regularities previously observed in the behavior of the linear term in N-c, of the spin-spin and of the spin-orbit terms. In particular the contribution of the spin-dependent terms decrease with the excitation energy, the dominant term remaining the spin-spin term.
